Slot milling cutter DIN 6527K Type N D.20mm VHM TiAlN (short) by TECWERK — solid‑carbide, TiAlN‑coated, 20 mm diameter

The Slot milling cutter DIN 6527K Type N D.20mm VHM TiAlN HB Z.2 kurz is a short, centre‑cutting solid‑carbide slot milling cutter designed for vibration‑reduced roughing and finishing across a wide range of steels, cast irons and non‑ferrous alloys

• Solid carbide (VHM) construction
• TiAlN coating for extended tool life
• Short, centre‑cutting design
• Suitable for steel, cast iron, non‑ferrous

High cutting performance with proven carbide and coating

This slot cutter combines a solid‑carbide body made from fine‑grain carbide with a TiAlN surface treatment to deliver superior tool life under elevated temperatures. The chemistry and microstructure of the carbide ensure consistent edge stability, while the TiAlN coating reduces friction and increases resistance to adhesion and wear. For production environments where cycle times and repeatability are paramount, this configuration offers an efficient balance between hardness and toughness, contributing to steady material removal rates and fewer tool changes.

Geometry that reduces vibration and improves surface finish

The tool features a short design with a centre‑cutting tip and a tailored neck relief to allow close engagement without chatter. The optimized flute geometry and variable helix reduce harmonic excitation, enabling more stable cuts even at higher material removal rates. As a result, the cutter supports a two‑pass workflow — roughing followed by a finishing pass — with improved workpiece integrity and reduced secondary operations. The design is particularly advantageous when working on thin‑walled components or interrupted cuts where vibrations normally compromise surface quality.

Broad material suitability for versatile shop use

Engineered for universal application, this cutter is well suited to a broad spectrum of materials: plain and alloyed steels, cast irons, stainless grades (INOX), non‑ferrous metals and aluminium alloys that contain silicon, as well as many abrasive materials and special alloys. The combination of fine‑grain carbide and TiAlN makes the tool especially resilient in mixed‑material production batches where tool wear can vary significantly. The result is fewer tool variants to keep in stock and a more streamlined production planning process.

Precision shank and standard conformity for easy integration

The cutter comes with a cylindrical shank manufactured to DIN 6535 HB with a 20 mm shank diameter and h6 tolerance, guaranteeing concentricity and reliable clamping in most toolholders. The DIN 6527 K, Type N standard ensures compatibility with existing tool inventories, and the short overall length aids rigidity for heavier cuts. These metrological and mechanical design features lower setup times and contribute to consistent process capability in both prototype and series production.

FAQ

What materials can this slot milling cutter handle best?
The TECWERK slot milling cutter (SKU 2000866171NW) is very well suited to a wide range of materials including steels, cast irons, stainless steels (INOX), non‑ferrous metals and aluminium alloys with silicon content, as well as many special and abrasive materials.

Is the cutter suitable for finishing as well as roughing?
Yes, the short, centre‑cutting geometry and TiAlN coating allow the cutter to perform both roughing and finishing operations with reduced tendency to chatter and good surface integrity.

What are the shank dimensions and tolerances for toolholder compatibility?
The tool features a 20 mm cylindrical shank manufactured to DIN 6535 HB with an h6 tolerance for precise clamping and concentricity in standard holders.

How does the TiAlN coating benefit machining?
The TiAlN coating increases thermal resistance, reduces adhesion, and lowers wear rates, which extends tool life during high‑temperature cutting and helps maintain cutting performance over longer runs.

Can this cutter be used for interrupted cuts or thin‑walled components?
Yes, the cutter’s variable helix and neck relief provide vibration damping and rigidity that support machining scenarios with interrupted cuts or thin walls, improving stability and finish quality.
